Application filed April 21, 1909. Serial No. 491,378.

To all whom it may concern:

Be it known that I, PLINY E. Hour, a citizen of the United States, and residing at 836 West Poplar street, in the city of Stockton, county of San Joaquin, and State of California, have invented certain new and useful Improvements in Plowing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the across the field, and having two sets of plo'w gang: capable of being raised and lowered and oth adapted tothrow their furrows in the same lateral direction.

' Broadly, the invention consists of 21; primary tractor located on one side of the machine and consisting of a traction belt. a

driving means therefor, a supporting t'ru'ck having rollers journaled therein and adapt-- ed to travel over the traction belt and support the main tractor frame; a secondary or auxiliary traction mechanism located on. the opposite side of the machine and mounted on an outrig er frame;a suitable power unit adapted to drive both traction mechanisms;

, supporting and steering wheel trucks adapted to partially support the plow gangs and pivotedto the mam frame and cross con nected with each other through a suitable steering mechanism; and a raising and low- 'ering mechanism for raising and lowering the plow gangs into and out of the operative osition.

In the drawings: Figure 1 is a side elevation of a plowing machine drawn to illustrate this invention. Fig. 2.- represents a plan-view from above of the-same. Fig. --3 is a front elevation illustrating one of the steering trucks.

In detail, the construction consists of a main tractor frame composed of the main beams 1 resting upon the supporting truck 2, in which the supporting rollers, 3, are journaled. The prune tractor consists of the traction belt 4 driven by the sprocket 5 from which the traction belt extends around and beneath the idle sprocket 6 mounted in one end of the supporting truck, thence under the supporting rollers 3, thence around the idle sprocket 7 mounted in the opposite end of the supporting truck, thence back to the drivin sprocket mounted upon the main frame an suitably geared to the motive unit 47. The secondary tractor consists of' the concentric wheel 8 mounted on the outrigger frame 9 and driven by the shaft 10 through a reducing gear by the motive unit 47; or by a traction mechanism similar to the primary tractor. The primary and secondary tractors are synchronously driven so as to hold the tractor in its course.

The-supporting and steering trucks consis't of the flan ed wheels 11 mounted upon the axles 12 p voted at 13in the outboard frame 14 fixed on the main frame. The axles 12 are cross-connected on opposite sides of the center by the rods 15 and 16 which are provided at their centers with flexible chains, 17, wrap ed around the drum 18, which is rotated y a worm gear, 19, fixed upon the steeringcolumu 20provided with the hand wheel 21. The wheels llare pro vided with the flanges 22, which are adapted to sink into the groundto prevent side slip. Through the use of the cross-connections the steering trucks are readily controlled and it is possible to swing 'the machinewithin a minimum of space.

The plow gangs consist of a series of plow bottoms, 23, mounted in gangs in the usual manner on oblique plow beams, 24, so ported on the furrow, or outer, side by t e furrow wheels, 25, and supported on the inner side by adjustable supports, 26, fixed to the axles 12., These, supports, 26, support reach bars," 27, pivotally 1 attached at one end-to'the forward ends of the oblique plow beams,-as at 40, and pivoted at the other end to-the main frame, as at 28; The furrow ends of the ,plow bea'ms are'similarly pivoted to the main frame, as at 29, by reach bars, 30.

To enable the machine to plow back and forth across the field without turning the tractor about, two sets of plow gangs, exaetly ahke m construction and support, are

provided at opposite ends of-the machine.

These plow gangs are alternately raised and.

lowered by the cable 31, the cnds of which are attached to [he plow beams, as at46, and

the intermediate portion of which is given several turns about the winch 32, which is operated by the worm gear 33 on the shaft 34 mounted on the superstructure 35 and provided with the hand wheel 36. The cable 31 traveling over the idler 37 and the winch 32 is ofsuch length that only one gang of plows can be in the operative position at any one time.

The suction of the plow points (that is the angle from the point 38 to the heel 39) is controlled by the reach rods 27 and 30 ivoted to the plow beam at 40, and provided with the screwadjustment 41 passing thereth-roughand provided with the running nuts 42 and 43 thereon, between which the reach rods'are locked in position to give the proper downward slant or suction to the plow points. This suction may be varied to suit thequality of the soil to be plowed, and may be adjusted to conform to the depth to which the plow penetrates into the soil.

In operation,.supposing the machine to be advancing to the left as illustrated" in Fig. 1,

the machine traverses the field leaving our open furrows (or more or less depending upon the number ofplows in the gang; in its wake. Having completedits trave in this "direction, the plows are raised-out of operative position by the manipulation of the winch 32. The tractor, controlled by the steering gear, is then advanced to the ri ht until the distance advanced equals the wi th of the furrows just opened. In this position the other gang of plows is lowered into operative position, the reverse gear Pi-is thrown -into reverse engagement, and the tractor travels back across the field over a new course parallel to the course of the firsttrip,

and turning up .furrows equal in width to those previously plowed and throwing them in the same lateral direction. While the tractor is coming into position or maneuvering inits course, the reach rod 27 'is free'to '45 slide laterally on the support 26, whereby the. course of the tractor can be altered or corrected without seriously -ail'ecting the course of the operative plow gang. The support 26 is provided with a seriesof holes,

45, which admit of vertical adjustment to regulate the depth to which the plow bottoms are permitted to (penetrate into the soil. After having traverse in this wise the land to be plowed, the land at the end of .the

' series of furrows remains unplowed because of the space required for maneuvering the tractor at the end of each trip.' The plow- -ing machine may then be thrown into a position to make sufiicient trips across the ends of the furrows to plow the remaining unplowed land. The location ofthe plow ang on the machijhe is such that it is possib e to run parallel and very close to a fence or a given line.

It is obvious that traction means other that various changes may be made without 7 materially departing from the spirit of this invention. It is apparent also that this ma-.

chine may be built so as-to include but one plow gang, though in so doing its effectiveness will be greatly limited. It has heretofore been the practice in the use ofdouble plows (that is to say two sets of plows adapted to throw their furrows in the same lateral direction) to mount the same upon supporting trucks which are towed back and so forth across the land by a'cable operated by windlasses on opposite sides of the land.
